After cleaning, the silicone tableware should be placed in a cool and ventilated place to dry, avoid direct sunlight and high temperature baking, to prevent discoloration and aging. In addition, the storage of silicone tableware should also pay attention to avoid long-term stacking or heavy pressure to prevent deformation or damage. It is worth noting that although silicone tableware has many advantages, in some special environments, its service life may be affected. For example, in humid, acid-base or strong oxidizing environments, silica gel materials may accelerate aging, resulting in decreased performance. Therefore, when using silicone tableware, you should try to avoid exposure to these harsh environments for a long time to extend its service life.   Even the best quality silicone tableware can't avoid aging over time. When the silicone tableware appears obvious discoloration, deformation or cracks, it should be replaced in time to ensure food safety. In addition, if the silicone tableware is found to emit odor or harmful substances during use, it should be immediately stopped and professional advice should be consulted. In order to extend the service life of silicone tableware, consumers can also take some additional maintenance measures. For example, when storing silicone tableware, it can be placed in a special tableware box or storage bag to avoid the attachment of dust and dirt. At the same time, regularly check the integrity of silicone tableware, timely detection and treatment of potential problems, is also an effective way to extend the service life.   With the progress of science and technology and the constant change of consumer demand, the design and manufacturing of silicone tableware are also constantly upgrading. Some new silicone tableware uses higher grade raw materials and more advanced production processes, which not only improves the durability and safety of the product, but also gives it more functions and characteristics.

A bad silica gel mold can produce the same appearance by shoddy, but it can not copy the design of a good product, whether it is good or bad, the eyes of consumers are sharp, and can be found in the process of use.   Secondly, the raw material of silicone products is also a major factor in determining the quality of silicone products. Silicone products have the characteristics of strong elasticity and durability, but if the use of bad rubber material, the service life will be greatly shortened, deformation will occur repeatedly, different rubber material has different performance, ordinary people only with the naked eye are not good or bad rubber material, the conscience of the manufacturer determines the quality of silicone material, the quality of silicone material determines the quality of silicone.   In addition, the vulcanization effect of silica gel also affects the quality. If you feel the uneven hardness and softness of the product, the tensile rebound strength is poor, and the rebound effect is poor, it is related to the manufacturer's vulcanization time and vulcanization process. Vulcanizing agent is divided into high temperature vulcanizing agent, low temperature vulcanizing agent, two vulcanizing agent can be combined to produce a good product, the production of reasonable choice, the use of vulcanizing agent, in order to produce a good silicone products.   Finally, manually grasp the quality control of the silicone produced, maintain the normal operation of the machine, improve the operation skills of the operator, and strengthen the training of quality awareness, which is also a factor that determines the quality of silicone products, and is the benefit of the enterprise.
